How can I get the result of an action and use it conditionally in my code?
As a very simple example:
package { "wget" : ensure => 'present' }
# if that failed, do X
To put this in context, some actual use cases I have:
- attempt to register an agent to a remote service and if that fails, open
a ticket via an API so it can be manually resolved
- attempt to create an LV and if that fails, call another module that adds
some new LUNs to my host, extend VG etc...
- ensure some critical service is running, but in case of any error raise
an alert via the standard alert API
- when applying some security-related code, confirm success/failure to a
compliance product API
